The present invention discloses a Physical Cell ID (PCI) allocation method and a base station. The PCI allocation method includes the following steps: a target base station obtains a usable PCI list sent by an Operations And Maintenance (OAM) function entity, and removes limited PCIs of the target cell from the usable PCI list to obtain a selectable PCI set (step S102); the target base station obtains the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) information of neighbour cells of serving cells via an X2 interface message, and obtains a first reference PCI set in a predefined manner, cell EARFCN information in the first reference PCI set is different from that of the target cell of the target base station (step S014); the target base station forms a second reference PCI set based on the intersection of the usable PCI list and the first reference PCI set (step S106); if the selectable PCI set is empty, then a PCI is randomly selected from the second reference PCI set as the target PCI (step S108). The success rate of the PCI allocation for the target cell is improved by the present invention. |
